How Do Greenhouse Gases Cause Climate Warming

How do greenhouse gases cause climate warming?

A) Infrared energy from space is absorbed by greenhouse gases in the upper atmosphere, which then re-emit the heat toward the surface of the earth, causing the climate to warm.
B) Greenhouse gases block solar energy from entering the lower level of the atmosphere.
C) Greenhouse gases prevent radiation of infrared energy back into space, trapping the heat near the earth's surface and causing the climate to warm.
D) Solar energy is absorbed by greenhouse gases in the upper atmosphere and re-emitted toward the earth's surface as heat, causing the climate to warm.
